Respect border settings when rendering lone tabbed/stacked child

In i3, when a child of a tabbed or stacked container has no siblings,
its border settings are respected.

This patch achieves the same effect by rendering a lone tabbed/stacked
child as if it's a linear container. This makes the border settings be
respected.

Over in view_autoconfigure, we compensate for this by only adjusting
`y_offset` if there's multiple children.
